PARIS: With air passenger numbers set to double to six billion annually by 2030, the world’s premier air show in Paris will next week focus on green issues even as the aircraft sales war remains center stage.

The Paris Air Show brings together some 315,000 visitors and 2,260 exhibitors from 47 countries, with much of the attention focused on which big manufacturers, particularly Airbus and Boeing, will land the most orders.

But the event happens to be hosted in the same Le Bourget venue outside Paris that will welcome world leaders later this year as they try to hash out a global deal to curb greenhouse emissions.

So it is little surprise that this year’s air show, running June 15 to 21, will put a special focus on environmental issues and innovations.
